DEAFENING OR FILLING FOR WALLS.

fPECIFICATION forming part of Letters Patent No. 311,567, dated February 3, 1835.

Application filed April 24, $84. (No model.)

To all whom it may concern.-

Be it known that I, LEONARD E. CLAWSON, of the city and county of San Francisco, and Stateof California, have invented an Improvement in Deafening or Filling for Walls; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a filling or deafening t'orwalls and partitions; and it consists of a filling and a means for introducing it between thestudding, as will be more fully explained by reference to the accompanying drawings, in which Figure l is a perspective view showing the mold or box. Fig. 2 is a horizontal section.

The usual manner of filling the spaces between the studding of partitions or walls for the purposeot'deafeningand preventingsounds from passingis by means of detached bricks or blocks of anysuitable material. These blocks must be laid up by a mason or brick-layer at a considerable expense and some waste of mate between them, I make abox consisting of two movable sides, the studding forming theends. These boards B are out to a length which will admit them between the studding, so that their outer faces will be flush with the outer faces of the studding. BarsCeXtendaeross outside these boards, their ends resting upon the stud ding, as shown, and holes D are made through them to receive bolts E, by which the parts are held in place. Strips F are nailed vertically upon the inside faces of the studding about midway between their outerfaces. Iron stay-rods G extend between the studding, as shown, to hold them together and keep the filling in place. These parts being in place, the filling material is mixed in a liquid form or plastic condition, and is poured into the mold thus formed, where it is allowed to set until hard. The bolts E are then withdrawn, the bars C and boards B removed and replaced above the sections thus formed, and the pro cess repeated until the whole space is filled. The bolts E are easily withdrawn, and without danger of breaking the filling material, which is held solidly in place by the stay-rods and strips F. By this method the filling is rapidly and cheaply introduced, there being no eartage of blocks, no breakage or Waste of material, and no expense for skilled labor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is l 1. The inclosure or mold consisting of the removable sides B,extending between the studding and held in place by the bars 0, and the bolts E,passing through the sides and bars and uniting the parts, substantially as herein described.

2. The studding A, with the vertical projecting strips F on the inner faces, and the stay-rods G, uniting the studding so as to pass through the interposed filling material, substantially as herein described.

In witness whereof I have hereunto set my hand.

LEONARD E. CLA\VSON.
